How did ancient humans see tall growing grass (wheat), think to harvest it, mill it, mix it with water then put the mixture into fire to make ‘bread’?

Question

I am trying to comprehend how something that required methodical steps and ‘good luck’ came to be a staple of civilisations for thousands of years. Thank you. (Sorry if this question isn’t correct for ELI5, I searched and couldn’t find it asked. Hope it’s in-bounds.)

Not too tricky. Birds eat seeds from grasses all the time. So we knew it was edible, we just didn’t know how. So one of the earliest developments would have been to boil it and eat it like cereal. After that it’s not much of a leap to grind it and make cakes, because that same cereal, when cooled, will become cakes anyway.
